Mantle cell lymphoma (MCL) is a distinct non-Hodgkin's lymphoma type that commonly affects extra nodal sites. The most often affected sites are bone marrow, gastrointestinal tract and Waldeyer's ring, being the skin rarely involved. We report a case of 56 year-old man with MCL, exhibiting multiple large maculopapular skin rashes and skin ulcers. Histopathological examination had not shown direct infiltration by any atypical cells. He had significant improvement of skin lesions with combination chemotherapy and debridement. Awareness of skin manifestations of MCL is crucial for dermatologists and haematologists to establish the early diagnosis and timely administration of appropriate treatment.
